Assignment 2: Personal and Corporate Computer Security Awareness and Countermeasures Continuing with your efforts to educate CSII employees, you now need to provide them with the most current information about personal and corporate computer security awareness and countermeasures. Most government agencies and employers post their own policies and procedures based on the experiences of their information technology (IT) security professionals and recommend countermeasures accordingly. Many of these government agencies and employers visit various websites (including but not limited to government websites) and offer and take advice from specialty organizations. Here is a list of websites to consider: The National Institute of Standards and Technology (NIST) at nist.gov/index.html The Computer Security Resource Center of the NIST at The SANS Institute at The CERT Coordination Center of the Software Engineering Institute at Carnegie Mellon University at ComputerSecurity/ Tasks: Using the Argosy University online library resources and the websites specified above, find three articles and analyze each on two of the following topics: Social engineering Shoulder surfing Password or passphrase best practices Hardware or software firewalls Antivirus protection

The proliferation of digital technology has heightened awareness of personal and corporate computer security threats. Effective cybersecurity measures are essential for safeguarding sensitive information, maintaining operational integrity, and preventing financial or reputational damage. This paper discusses the importance of two critical topics—password or passphrase best practices and hardware or software firewalls—and synthesizes information from three scholarly articles on these subjects.

Understanding Password or Passphrase Best Practices

Password and passphrase security remains a cornerstone of cybersecurity due to the prevalent threat of unauthorized access. A password is a secret string of characters used for authenticating user identity, while a passphrase is a longer, more complex string that often incorporates multiple words or phrases. In everyday life, passwords serve as the primary defense for accessing personal accounts, work systems, and financial data (Florêncio & Herley, 2010). Effective password practices involve creating strong, unique passwords that are difficult for attackers to guess or crack. Recommendations include the use of a mix of uppercase and lowercase letters, numbers, and symbols; avoiding easily accessible personal information; and employing password managers to generate and store complex passwords securely (Bonneau et al., 2012).

Similarly, recent articles emphasize the importance of passphrases in enhancing security. Unlike traditional passwords, passphrases tend to be longer and easier to remember, making them more resistant to brute-force attacks (Pearson et al., 2017). Both articles agree that regular password updates are essential, but they differ slightly in their advice: some recommend changing passwords periodically, while others suggest only changing them after suspected compromise (Das et al., 2014). Variability in best practices reflects ongoing debates within the cybersecurity community about balancing security and usability.

Understanding Hardware or Software Firewalls

Firewalls act as a barrier between trusted internal networks and untrusted external networks, such as the internet. Hardware firewalls are physical devices placed between a network and its connection to the outside world, offering network perimeter protection (Raghavan & Phipps, 2005). In contrast, software firewalls are installed on individual computers or servers, providing tailored security controls for that specific device and enhancing defense against internal threats or malware (Kumar et al., 2018).

The articles concur that deploying both types of firewalls creates a layered security approach, increasing resilience against intrusion attempts. Hardware firewalls are praised for their robustness and ability to monitor large volumes of traffic, while software firewalls provide granular control and are crucial for endpoint security (Zhou et al., 2020). Discrepancies arise in recommendations about configuration: some emphasize the importance of strict rule sets and monitoring, while others suggest a more flexible approach to allow necessary business operations without compromising security (Johnson & Turner, 2016). The consensus underscores the importance of continuous updates and monitoring in maintaining effective firewall defenses.

In conclusion, the reviewed articles highlight that best practices in password management and firewall deployment are vital components of a comprehensive cybersecurity strategy. Adopting strong, complex passwords and passphrases, coupled with layered firewall defenses, significantly reduces vulnerability to cyberattacks. While scholarly perspectives differ on certain procedural details, the shared goal is to foster a security-aware culture that prioritizes proactive measures, continuous monitoring, and user education to mitigate evolving threats.
